That is actualy an old Turkish Custom when buying rugs from a merchant... they offer you turking coffee or apple tea and haggle with you over a price.. It's the polite thing to do, offer your customer refreshments before you charge them up the ass.
Quote O' Matic
Gino: I noticed a lot of boxing memorabilia, trophies, pictures, and gloves on the counter. Who's the boxer?
Bartender: Me.
Gino: Really? You a tough guy?
Bartender: Tough enough.
Gino: Really? What could you do?
Bartender: To you?
Gino: Yeah.
